Audio Processing

2. The audio communication apparatus of claim 1, comprising a data connection to connect the set of two or more audio communication nodes for the transmission of encoded audio data between audio communication nodes of the set.

3. The audio communication apparatus of claim 1, in which the audio encoders of the set of two or more audio communication nodes are identical and use the same encoding parameters.

4. The audio communication apparatus of claim 1, in which each audio communication node is configured to provide decoding parameters associated with the user of that audio communication device to another audio communication node configured to receive encoded audio data from that audio communication node.

6. The audio communication apparatus of claim 1, in which each audio communication node comprises an entertainment device configured to execute a computer game.

9. The machine-implemented method of claim 8, in which the artificial neural network (ANN) training steps comprise generating a set of learned parameters to control operation of at least one of the ANN to act as the user-agnostic audio encoder, and the ANN to act as the user-specific audio decoder.
